Check Digit Verification of cas no

The CAS Registry Mumber 205309-89-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,5,3,0 and 9 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 205309-89:
(8*2)+(7*0)+(6*5)+(5*3)+(4*0)+(3*9)+(2*8)+(1*9)=113
113 % 10 = 3
So 205309-89-3 is a valid CAS Registry Number.
